Winit shipping is usually about 5 weeks for me. Their tracking is useless in the US. It ends once the package reaches the POE. USPS China Post is much quicker. I just got one that came in 10 days. SpeedPAK only takes about two weeks.
I like the milk carton containers. They pack tight, give good depth and the plants can't root tangle if left for a few months til plant out. The bagged plants would all grow together into a big lump without separation.
I can send you a quarter inch of bags as an Int'l letter in the unmarked envelope containing the Valentine my wife gave me this morning. That will be cheap and at least you'd get to see the bags if you're not familiar with them.
I have no idea what I am going to do DW...I still need to start my tomater's and my bell peppers both of which we eat alot....THEn the various other stuff I wanted to start earlier this year as well. Alot of random vegis I can just window sill it if I have to. I have a feeling the very bottom shelf is going to come into play here this year, the light wont be as good but better then nothing.
Fortunately, I have plenty of nursery space for all my stuff even with cutting down from 24 plants per bin to 12 per bin to give them more space Still, I will be running at least two of the three areas until planting because of catch up light cycles and starting even more plants like my squashes and green beans. Some other stuff like herbs and lettuce will go into planter boxes when the time comes.
My big problem is gonna be trying to figure out where to put everything. My isolation peppers will grow in small pots away from the garden and some of the squashes will grow in tire beds. I'll put some peppers and tomatoes in my 15 gallon pots this year. .Sadly, I think I may do away with a few of my old timers I've overwintered for years.
